If it's the hose I think you're talking about it goes into the water tank compartment behind the drop down door (with the two pumps and two portholes in the plastic cover behind the door). In my 364, the pipe runs through the water tank compartment with a "T" in the line that is open into the compartment. The rest of the hose seems to go up into the floor to feed the hallway/bathroom vents. I tried to plug the T and got most of the air diverted into the hallway. Still don't have any noticeable flow into the bathroom.
There is quite a bit of hose looping around under the shower though, so I wonder if that hose has a kink in it or something.
